I'm planning on running the RTTY Roundup next Jan. at the allowed 150w level to see what difference it makes. I have an Inrad triplexer that has served well at 100w RTTY, and is rated at 200 watts. I'd feel better if someone has run one RTTY at 150 without issue. Mark. N2QT PS I know it won't take 1500 watts, tried that.
